Just one week on from the release of a number of lightly-camouflaged photos, Lamborghini's ordering guide for its upcoming Murcielago-replacing LP 700-4 - rumoured to be named 'Aventador' - has made its way online.

Obtained by performance enthusiast website TeamSpeed, the ordering guide offers a comprehensive rundown of the new Lambo's specifications, including power, weight and - perhaps most importantly - its performance figures.

If the leaked images are to be believed, the LP 700-4 will hustle to 100km/h in just 2.9 seconds, making it 0.3 seconds quicker than the most powerful model in the now-retired Murcielago line; the LP 670-4 SuperVeloce.

The numbers also show that the new Lambo hero car is larger in almost every direction, measuring 4780mm long, 2030mm wide and 1136mm tall. Its wheelbase is also longer, measuring 2700mm to the Murcielago's 2664mm.

As promised, new lightweight construction practices have brought the LP 700-4 down to 1575kg, compared to the Murcielago's 1650kg.

Holding up each corner will be 20-inch wheels at the back, wrapped in 335/30 tyres and 19-inch wheels at the front, shod with 255/35 tyres. Braking is managed by 16-inch discs at the front with six-piston calipers, and 15-inch rear discs gripped by four-piston calipers.

Among the LP 700-4's options will be a carbon-fibre engine cover, coloured calipers and suspension springs, along with a range of wheel designs.
